Pre 1950s rides of LFGSS: old bikes, vintage rats, classic lightweights

Your so patient, I probably would have destroyed the frame by now...
trying to get the seat post out.!
It looks like your patience is going to pay off though. Keep us posted.

Keep us posted.

Lol

Fuuuuuuuuuuuuucckkkkkk
Bumped into the frame.
The seal failed, cue a high pressure spray of vinegar, plus-gas and rust all up one wall and the ceiling and me.
Indoors.
Not a garage indoors.
Indoors the house.
This weekend I will now be mostly redecorating.
And the feckety fecking seat pin is still stuck. Fml.

Ouch.

Oh shit that sounds horrible, Rust Vinegar Fountain.

Room now stinks as well.
Gah, what an idiot.
Luckily it happened while I’m at home.
Coming back to a worse mess - because it would have failed, likely soon - as the frame launched itself like a firework around the house. Doesn’t bear thinking about.

I'm very sorry to hear about this.

No one considered the implication of the sealed seat tube - with a conventional frame there is no pressure build up because the gas escapes through the bottom bracket shell.

It's disappointing that the pin is still stuck, but it's clear that the method is working - given enough vinegar and a lot of patience (mainly from other family members !) that pin will either come out or dissolve completely. If you do carry on you will need to relieve the pressure from time to time.

I can only offer my apologies for the mess.

Lol, it’s not your fault, basic chemistry (physics?) fail on my part.
For the sake of domestic bliss I think I need to leave it for a bit. Or until I can leave it outdoors for a bit for regular ‘venting’ ha ha.
I’d take it to the Seatpost Man if it wasn’t a ten hour round trip. I’d rather not trust the frame to the tender mercies of couriers…

It may be obvious, and a little drastic, but is there no way you can hacksaw through the seatpost top, leaving a good 'stump' of it standing proud of the frame, then saw dow vertically into it with just a junior hacksaw blade? You could then try crushing the remainig (cut through) 'stump' of seatpost until it mishapes and comes loose? It would take a lot of patience, effort and above all care not to damage the frame/paint etc but i'm pretty sure it could work? Better than heating the tube etc and damaging paint maybe?

I'm pretty sure i tried this with my old carlton's original stem, although tbh i can't remember if that was worked in the end or not.

Use a standard hacksaw blade in pull mode - so it cuts when you extract. Wrap a cloth on the blade to act as a handle. Put a nut n bolt through the blade hole inside the frame - pick one so that it stops the blade cutting the frame once you are through the post. It's generally 1+hrs work, but your arms will fall off well before then - so spread it over 2 days. You will have to make 2 cuts to get the blighter out. Have a torch handy to check your progress. Get a sharp and course (18tpi) blade.

As you may have gathered, I'd done this more times that I care to recall ;-)

Thanks all for the suggestions on cuttin-n-shuttin:)
It’s something I’ve done once on a far, far less valuable and thicker gauge frame. And my arms did feel like they were going to fall off lol
The wall on this is super-thin. I don’t trust myself to do it.
Will have a ponder.

Judging by your photos there's a lot of that seat pin in the frame (there's not much of a length above the frame). So you would need to make a long cut (or cuts) in the pin, which would be tedious even though perfectly feasable.

Possibly something which is more aggressive with the ali might help. However I'm convinced vinegar will work given enough time.

@crossedthread
Where are you based?
Parents live close to seatpostman,I may be able to get it there and back if you aren't in a rush.
Drop me a pm if I can help.

:)

Beauty

For the sake of domestic bliss I think I need to leave it for a bit.

This gave me a real snorting laugh out loud. I feel your pain and thank you :)

That’s certainly a tempter.

There’s some decent Strata pedals on Ebay with a buy it now of £80. A bit toppy but nice pedals.

I’ll beat @SideshowBob to this one …

Worth so much more.

If I had more space, more money, less projects already on the go, I'd be in for that track frame.

Oh I'd be in for both!!

But I meant the Hobbs is worth more than the seller's asking price.
